Application filed Februaryg, 1928. Serial 1 To.'252,972.

This invention relates to looks.

In the ordinary construction of door closures provided with springlatches, a knob is generally provided, spaced from the edge of saiddoor. Where it is desired to mountan additional means for locking thedoor fixedly in position, as, tor instance, bolts moving parallel to thevertical. edge of the door, it is desirable to have said bolt-spositioned close to the edge of the door in order to avoid contact withsaid knob, and also to facilitate the locking action. To carry out thispurpose, the present invention provides a l-ock-' mg means wherein abolt 18 pro ected into engagement with a strike, and additional boltmeans is positioned to extend along the vertical edge of a door,together with novel actuating means for the last mentioned bolts,operated by the first. named bolt.

An object of the invention is to provide a simplified locking mechanism,capable of projecting a plurality of bolts in several directions, soassembled that operating means for some of the bolts may be located atany point within a lock casing, within certain limits, in order thatsuch bolts may,'if de' sired, be positioned along an edge of a closure.

Another object of the invention is to provide a novel lock means forprojecting and locking bolts, operated by a single key of the ordinarytype, without the necessity of using an auxiliary locking mechanism.

A further object of the invention is to provide a lock adapted toproject bolts in a plurality of directions, said lock being adapted formounting in any one of a plurality of positions without. change in themechanism thereof.

A still further object of the invention is to provide a lock forprojecting lockbolts in opposite directions, said bolts being insubstantially the same plane, yet being capable of manufacture withoutbending, and withan ordinary key may be used for its actuation.

A still further object of the invention is to provide a locking devicefor projecting a plurality of bolts, in which a single key both projectsand locks these bolts in position.

Other objects of this invention will in part betobvious and in parthereinafter pointed on The invention accordingly consists in thefeatures of construction, combinations of elements, and arrangements ofparts whichwill be exemplified in the construction hereinafterdescribed, and of which the scope of ap-' plication will be indicated inthe following claims.

On the drawings, a lock comprises a lock casing C adapted forco-operation with a strike or keeperK, said casing being formed in anysuitable manner, as by casting,'so as to provide the body portion 14 anda cover portion 16. Said bodyportion comprises a lull base 10 and anupstanding peripheral wall 12, which may be open at the front end 11thereof. Body portion 14 may have integrally formed therewith theupstanding lugs 18, 20, adjacent the end 11, said lugs being formed withthe semi-circular cut-outs 22. Corresponding lugs 19, 21, are providedto extend from cover 16 and have cut outs 23 provided therein to matewith cut outs 22 and form circular bearing openings. A bolt 24 isreceivable through said cut-outs and has one end connected in anysuitable manner, or made integral with, a cross head 26, said cross headco-operating in a manner hereinafter described, with a device forimparting reciprocal motion thereto. The free end of bolt 24 is receivedin opening 28, which may be formed in a lug 30 integral with the base 10of body portion 14 adjacent end 11 thereof, or in a wall whichmay extendacross said frontend of the lock casing C.

A strike or keeper Kmay likewise be made of a single casting, having aprojecting portion 34, formed with an opening 36 transversely entendingtherethrough. In that construction wherein thelock casing C ends with awallat end 11 through which a bolt 24 e2:- tends, projecting portion 34will be positioned eXternall'yof casing C, so that, when casing C ismoved into position adjacent strike K, and bolt 24 is projecting throughopening 28 said bolt will enter opening 36 to engagethe strike. However,in the preferable construction, as shownon the drawing, base 10 of thecasing may'beformed to receive portion 84 therewithin by having anextension 88 made integral with base 10, said extension being providedwith an upstanding wall 40 which connects with the wall 12 of casing C.A slot 44 is formed in extension 38 and is designed to receive portion34 therethrough, so that said portion will be positioned and retainedrelative to bolt 24, in such mannerthat said bolt may properly engagewith opening 36 to lockthe parts together when the bolt is projected.

Carried on bolt 24 and retained between the upstanding lugs 18, 20, is agear 46 which has a through passage 48 formed transverse the plane ofrotation 01" said gear for receiving said bolt with which it has asubstantially smooth sliding lit. A pin 50 extends inwardly from gear 46into passage 48 and is received in a helical groove 5.2,cutin thesurface of bolt 24. Said gear is adapted to have drive engagement-withbars 54, 56, the en'- gaged ends of which are reduced in section, as at58, said reduced ends having raclrteeth cut therein for cooperation withthe teeth of gear 46. It will thus be seen that, on reciprocation ofbolt 24 into and out of engagement with strike K, pin 50 will beactuated by groove 52 to'slide bars 5'4 and 56transversely of casing C.The free ends of bars 54 and 56 may 'be formed as bolts 'to be suitablyreceived in properly positioned engagement members, as, for instance,sockets provided in the upper cross-piece and the threshold of adoorway. In order to provide against accidental or unauthorizedseparation or" said rack ends 58 from gear 46, said ends are formed withenlarged portion 62, adapted to IEngage gear 46 to limit movements ofsaid ars.

Bar 56 may have an offset portion 64 to connect its rack end 58 with thebar so that said bars 54 and 56 may slide in the same plane, and alongthe same line. By this means, there are provided lock bars sliding inthe same line and in the same plane, operable by a very simplemechanism, occupying very little space; so that the lateral andlongitud-inal dimensions of the lock casing C may be substantiallyreduced.

If desired, the offset 64 may be within casing (has shown in thedrawings. However, 'wiere such otlset is housed within casing C, arecess 66 in bar 56 for receivingthe rack'end 58 of bar 54 must beprovided. To properly guide bars 54, 56, in addition to the walls of theupstanding lugs 18, 20, there is provided the projection 68 formed aboutan opening 69 'in wall 12 of casing C. In making up bars 5-4, 56 it isfound desirable, because of the-ditferen't sizes of doors with whichthese bars are adapted to cooperate, to make the bars sectional. Aportion 70 of the bars 54, 56 is adapted for retention entirely withincasing C, or projection 68, at all times. Additional bars? 2 may besecured to portion 70 by having countersunk rivets applied, or by ascrew connection. In the latter case, a countersunk screw is used andhas its head positioned so that it will ride on the side of the locksecured to the closure. A straight rivet connection may be used wherethe projection 68 is provided; in such construction, said projectionprotects the joint between portion 7 O and bar 72 against unauthorizedtampering. How ever, where the countersunk rivets or screws are used,projection 68 may be eliminated and guides 7 4, 76 on either side ofbars 54, 56 may be cast integral with body portion 14.

As shown on the drawings,cross head 26 is formed with an ofiset guide 78 having an extending lug 80 received in a longitudinal slot 82 in thebase 10 of body portion 14. As additional guide means, a bearing point'84 is formed on guide 78 and rides along the guide surface 86integrally formed with base 10 so that said cross head is substantiallyguided for rectilinear motion.

Guide 7 8 is provided with a pin 88 extending laterally therefrom andhaving pivotally mounted thereon a locking finger 90. Said finger, atone end, is formed with a "double acting catch 92 having the engagingsurfaces 94, 96,for purposes hereinafter appearin g. The other endofsai'd catch isprovided with an inturnedarm'93, received in a recess 95formed in guide 78. Said inturned arm has a cam surface 98 adapted to beengaged either by a crank arm 100 secured to the barrel 102 of the keyoperated by device 104 or by a similar arm 101 actuated either by afinger knob or key actuated means mounted through the side of dooropposite barrel 102.

Said key operated device may be of any ordinary type, preferably havingthe pintumbler mechanism commonly in use, and being provided with a faceplate 106 received flush on the cover portion therefor. It will be seenthat upon insertion of a key (not shown) through opening 109 and thenturn ing said key, barrel 102 and its attached arm 100 will be rotatedso that said arm will contact cam surface 98 and rock the locking finger90 on its pivot pin 88 to release catch 92, as hereinafter appears.

A coil spring 110, wound around pin 88 and having engagement withhearing point 84 and a portion of finger 90, will normally tend toreturn said finger into a position in which catch 92 will engage a partof stop piece 112 to lock movement of guide 78 at a certain point. Stoppiece 112 preferably formed integral with base 10 is positioned so that,when cross head 26 is retracted as shown in Fig. 4 and bolt 24 is housedentirely within opening 28 and does not extend outwardly therefrom,surface 94 of catch 92 will have engagement with one edge 114 of piece112. When cross head 26 has been projected, in a manner here-- inafterappearing, so that bolt 24 fully enopening 28, the other surface 96 ofthe catch will engage an edge 116 at the other end of slide 112. It willthus be seen that finger 90 with its engaging surfaces positively locksthe bolt 24 and its connected devices against reciprocation at thelimits of their movement.

To actuate cross head 26 in order to move bolt 24 into engagingposition, the arm 101 rotated so that surface 94 is disengaged from edge114, finger 90 being moved against the action of spring 110. Continuedmovement of arm 101 will bring it into contact with cam surface 120formed as a part of cross head 26 and supply sufiicient force to propelcross head. 26 and its connected devices, so that bolt 24 and bars 54,56, will be pro jected into engagement with their respective parts.Finally. the end 118 of crank arm 101 will slide off surface 120 andrelease the cam 98 so that finger 90 under action of spring 110, will bemoved to bring surface 96 into engagement with edge 116.

In retraction of cross head 26, arm 101 is rotated reversely, and end118 is brought into contact with surface 98 to depress finger 90 andrelease catch 92. Continued application of force to arm 101 brings itinto engagement with the surface 122 so that cross head 26 will be movedback. Arm 100 will finally ride over surface 122 to clear arm surface98,

catch 92 riding along stop piece 112 in the meantime. Catch 92 will nowengage edge e is provided with an indent 136 into which end 118co-operates to notify the user that it has arrived at the full position,whether open or closed.

Body portion 14 may be provided with any suitable countersunk boltreceiving openings 188 positioned in a line with threaded openings incover 16, bolts cooperating with these openings to retain the co er 16on body portion 14, said cover being formed to co-operate with theguides on base 10. Additional openings 144 may be provided through base12 and cover 16 to receive suitable fastening screws to secure theentire lock casing to the support with which the lock is associated. Thebody of strike or keeper K may likewise be formed with countersunkopenings 148 to receive suitable means to fasten said strike to a partto be locked.

In the use of the lock illustrated in Fig. 7, there is shown a lockcasing C mounted to project the bars 54 and 56, the bar 56 beingreceived through the guide bracket 150 and having pivoted intermediatelythereon the two bolts 152, 154, of the type shown and tie scribed in myaforesaid co-pending application. The guide 150 is provided with thespring retention means 156 for bolt 154, said means also constituting afulcrum for bolt 152. Suitable brackets 158 and springs 160 co-operatewith the bars 54, 56 to substantial- 1v relieve the key actuated bolt inlook casing C of the weight of the bars 54, 56.

In the modification shown in Figs. 5 and 6, and assembled asillustrated, wherein the invention is applied to the use of short boltsfor conjunction with the ordinary door strike, the rack ends 162, 164,are guided by the upstanding port-ions 166, 168 formed integral with thecasing base. Extending substantially perpendicular to the ends 162, 164are the connectors 170 from which project the bolt ends 172. These boltends are positioned to be received in openings 17 4 in the strike lugs17 6, here shown as projected substantially perpendicularly to the planeof lug 178, which is adapted to co-operate with the bolt 24. The base180 of lock casing 182 is shown as pro vided with additional openings184 to receive the lugs 17 6 therethrough in the same manner as portion34 is received within opening 44. It will thus be seen that the threebolts will nultaneously eo-operate with strike 186, substantially in amanner snnllar to the operation of the bolts and bars shown in lugs. 1to 4.

It will thus be seen that there is provided a ing drawing is to beinterpreted as illustrative and not in a limiting sense.
